СКАЧАТЬ of her store will generally make it suffice for all man's needs and requirements. Sometimes this has been effected in a thirsty land by conducting all the rills and brooks that flow from the highlands or hills into subterranean conduits, where they are shielded from the sun's rays, and prolonging these ducts for miles upon miles, till every drop of the precious fluid has been utilized for irrigation. Such is the kareez or kanat system of Persia. In other places vast efforts have been made to detain the abundant supply of rain which nature commonly provides in the spring of the year, to store it, and prevent it from flowing off down the river-courses to the sea, where it is absolutely lost. For this purpose, either huge reservoirs must be constructed by the hand of man, or else advantage must be taken of some facility which nature offers for storing the water in convenient situations. Valleys may be blocked by massive dams, and millions of gallons thus imprisoned for future use, as is done in many parts of the North of England, but for manufacturing and not for irrigation purposes. Or naturally land-locked basins may be found, and the overflow of streams at their flood-time turned into them and arrested, to be made use of later in the year.

      In Egypt the one and only valley was that of the Nile, and the one and only stream that which had formed it, and flowed along it, at a lower or higher level, ceaselessly. It might perhaps have been possible for Egyptian engineering skill to have blocked the valley at Silsilis, or at the Gebelein, and to have thus turned Upper Egypt into a huge reservoir always full, and always capable of supplying Lower Egypt with enough water to eke out a deficient inundation. But this could only have been done by an enormous work, very difficult to construct, and at the sacrifice of several hundred square miles of fertile territory, thickly inhabited, which would have been covered permanently by the artificial lake. Moreover, the Egyptians would have known that such an embankment can under no circumstances be absolutely secure, and may have foreseen that its rupture would spread destruction over the whole of the lower country. Amenemhat, at any rate, did not venture to adopt so bold a design. He sought for a natural depression, and found one in the Libyan range of hills to the west of the Nile valley, about a degree south of the latitude of Memphis—a depression of great depth and of ample expanse, fifty miles or more in length by thirty in breadth, and containing an area of six or seven hundred square miles. It was separated from the Nile valley by a narrow ridge of hills about two hundred feet high, through which ran from south-east to north-west a narrow rocky gorge, giving access to the depression. It is possible that in very high floods some of the water of the inundation passed naturally into the basin through this gorge; but whether this were so or no, it was plain that by the employment of no very large amount of labour a canal or cutting might be carried along the gorge, and the Nile water given free access into the depression, not only in very high floods, but annually when the inundation reached a certain moderate height. This is, accordingly, what Amenemhat did. He dug a canal from the western branch of the Nile—the modern Bahr Yousuf—leaving it at El-Lahoun, carried his canal through the gorge, in places cutting deep into its rocky bottom, and by a system of sluices and flood-gates retained such an absolute control over the water that he could either admit or exclude the inundation at his will, as it rose; and when it fell, could either allow the water that had flowed in to return, or imprison it and keep it back. Within the gorge he had thus at all times a copious store of the invaluable fluid, banked up to the height of high Nile, and capable of being applied to purposes of cultivation both within and without the depression by the opening and shutting of the sluices.

      So much appears to be certain. The exact size and position of Amenemhat's reservoir within the depression, which a French savant was supposed to have discovered, are now called in question, and must be admitted to be still sub judice. M. Linant de Bellefonds regarded the reservoir as occupying the south-eastern or upper portion of the depression only, as extending from north to south a distance of fourteen miles only, and from east to west a distance varying from six to eleven miles. He regarded it as artificially confined towards the west and north by two long lines of embankment, which he considered that he had traced, and gave the area of the lake as four hundred and five millions of square mêtres, or about four hundred and eighty millions of square yards. Mr. Cope Whitehouse believes that the water was freely admitted into the whole of the depression, which it filled, with the exception of certain parts, which stood up out of the water as islands, from one hundred and fifty to two hundred feet high. He believes that it was in places three hundred feet deep, and that the circuit of its shores was from three hundred to five hundred miles. It is to be hoped that a scientific expedition will ere long set this dispute at rest, and enable the modern student distinctly to grasp and understand the great work of Amenemhat. Whatever may be the truth regarding "Lake Mœris," as this great reservoir was called, it is certain that it furnished the ancients one of the least explicable of all the many problems that the remarkable land of the Nile presented to them. Herodotus added to the other marvels of the place a story about two sitting statues based upon pyramids, which stood three hundred feet above the level of the lake, and a famous labyrinth, of which we shall soon speak.

      Whether the reservoir of Amenemhat had the larger or the smaller dimensions ascribed to it, there can be no doubt that it was a grand construction, undertaken mainly for the benefit of his people, and greatly conducing to their advantage. Even if the reservoir had only the dimensions assigned to it by M. de Bellefonds, it would, according to his calculations, have contained water sufficient, not only for irrigating the northern and western portions of the Fayoum throughout the year, but also for the supply of the whole western bank of the Nile from Beni-Souef to the embouchure at Canopus for six months. This alone would in dry seasons have been a sensible relief to a large portion of the population. If the dimensions exceeded those of De Bellefonds, the relief would have been proportionately greater.

      The pyramid intended is probably that examined by Perring and Lepsius, which had a base of three hundred feet, and an elevation, probably, of about one hundred and eighty-five feet. It was built of crude brick mixed with a good deal of straw, and cased with a white silicious limestone. The same material was employed for the greater part of the so-called "Labyrinth," СКАЧАТЬ
